MC33762: Dual Low Noise, Low Dropout Linear Voltage Regulator with 1.0 V ON/OFF Control
The MC33762 is a dual low dropout (LDO) linear voltage regulator featuring excellent noise performances. Thanks to its innovative design, the circuit reaches an impressive 40 µVRMS noise level without an external bypass capacitor. Housed in a small µ8 package, this linear voltage regulator represents the ideal designer's choice when space and noise are at premium.The absence of external bandgap capacitor accelerates the response time to a wake-up signal and keeps it within 40 µs, making the MC33762 LDO linear voltage regulator a natural candidate in portable applications. The MC33762 also hosts a novel architecture which prevents excessive undershoots in the presence of fast transient bursts, as in any bursting systems. Finally, with a static line regulation better than -75dB, it naturally shields the downstream electronics against choppy lines.
